AI trailer generator for movies that don't exist yet

The short answer

A trailer is the easiest movie to make with AI: 30 to 60 seconds of rising tension that never has to explain the ending. On StreamingWars, write a premise, pick a genre such as thriller or action, and ask for a trailer in your idea. The storyboard cuts it like one: a hook, quick escalating shots and a closing sting.

Why trailers suit AI shorts

Trailers are built from short, punchy shots, which is exactly how AI video films best. They promise a story instead of finishing it, so you get drama without needing two hours of plot. And they invite a sequel: if people want the movie, Watch more can turn the trailer into Part 1 of a series.

Cut it like a trailer

  1. 01

    The calm, first 5 seconds

    An ordinary world: a family dinner, a quiet office, a small-town diner.

  2. 02

    The crack

    One thing is wrong. A phone call, a stranger, a power cut.

  3. 03

    The climb

    Faster cuts, bigger stakes, one line of dialogue that sticks.

  4. 04

    The sting

    A last shot after the build-up: a reveal, a scream, a smile that shouldn't be there.

Write “a trailer for” at the start of your idea and the storyboard will cut it this way. Pick 30 seconds for a teaser, 60 for a full trailer.

Keep it original

Fan trailers for real films and famous characters aren't allowed. Invent your own movie, give it a title that sounds like a poster, and let the crowd decide whether they'd buy a ticket.

Questions people ask

How long should an AI trailer be?

30 seconds for a teaser, 60 seconds for a full trailer. Both fit easily on StreamingWars.

Can I make a trailer for a real movie?

No. Real films, real people and famous characters are off limits. Original movies only.

Can my trailer become a movie?

In a way. Viewers can tap Watch more and anyone can make Part 2, which continues from the trailer's last frame.

Make a short. Put it in the ring.

Two shorts. You pick. Winner climbs.
